The XATxConnectionManager connection manager has to perform the following operations:
1. When an application component requests a new ConnectionHandle,
it must find a ManagedConnection, and make sure a
ConnectionEventListener is registered. It must inform the
CachedConnectionManager that a connection handle has been given
out. It needs to count the number of handles for each
ManagedConnection. If there is a current transaction, it must
enlist the ManagedConnection's XAResource in the transaction.
Entry point: ConnectionManager.allocateConnection.
written.
2. When a ConnectionClosed event is received from the
ConnectionEventListener, it must reduce the handle count. If
the handle count is zero, the XAResource should be delisted from
the Transaction, if any. The CachedConnectionManager must be
notified that the connection is closed.
Entry point: ConnectionEventListener.ConnectionClosed.
written
3. When a transaction begun notification is received from the
UserTransaction (via the CachedConnectionManager, all
managedConnections associated with the current object must be
enlisted in the transaction.
Entry point: (from
CachedConnectionManager)
ConnectionCacheListener.transactionStarted(Transaction,
Collection). The collection is of ConnectionRecord objects.
written.
4. When a synchronization beforeCompletion event is received, any
enlisted XAResources must be delisted.
Entry point: Synchronization.beforeCompletion() (implemented in
XAConnectionEventListener))
written.
5. When an "entering object" notification is received from the
CachedConnectionInterceptor, all the connections for the current
object must be associated with a ManagedConnection. if there is a
Transaction, the XAResource must be enlisted with it.
Entry point: ConnectionCacheListener.reconnect(Collection conns) The Collection
is of ConnectionRecord objects.
written.
6. When a "leaving object" notification is received from the
CachedConnectionInterceptor, all the managedConnections for the
current object must have their XAResources delisted from the
current Transaction, if any, and cleanup called on each
ManagedConnection.
Entry point: ConnectionCacheListener.disconnect(Collection conns).
written.
In addition it inherits behavior from BaseConnectionManager2, including
functionality to obtain managed connections from
a ManagedConnectionPool mbean, find the Subject from a SubjectSecurityDomain,
and interact with the CachedConnectionManager for connections held over
transaction and method boundaries. Important mbean references are to a
ManagedConnectionPool supplier (typically a JBossManagedConnectionPool), and a
RARDeployment representing the ManagedConnectionFactory.
